Re: Purdue FOSCEC Season 3

Good news! EXchess did not crash in its last game of the tournament. I just noticed this post, and I am wondering if you can help me track down the problem. I don't have this issue on my systems, and I haven't had a crashing report from others, so this is a bit of a surprise, but if it is something...

Re: Crafty 25.0 Release

* Added the "counter-move" heuristic for move ordering (Jos Uiterwijk, JICCA) which simply remembers a fail high move and the move at the previous ply. If the hash, captures or killer moves don't result in a fail high, this move is tried next. No significant cost, seems to reduce tree size ...
